Abstract
A fiber optic diffuse light reflectance sensor is disclosed. The sensor employs illumination optical fibers to carry light emitted from a high-intensity, narrow bandwidth LED to a baffle in a readhead where the optical fibers reflect the light off of a reagent test strip. The illumination optical fibers are randomly oriented to create a more uniform light source. The light is reflected off of a pad on a reagent test strip to detect the presence of non-hemolyzed trace and hemolyzed occult blood. The reflected light must pass through another baffle to a bi-convex lens where it is focused onto a detection bundle of optical fibers. The detection bundle is optically coupled with a CCD, where the optical signal is converted to an electrical one for processing and analysis.
